TPI with a half-round bit.
I was wondering about doing that recently for a similar application
but when I looked my local farm supply had chipping hammers with
coil spring handles for £1.70 UKP (about $2.60) so just bought one

The stainless wire door handle doesn't feel hot in a location where
previous wood handles slowly carbonized. jsw
